Title: Ink-ribbon cartridge with reloadable ink-ribbon spools
Inventor: KEITER ALFRED
IPC: B41J32/00
Filed: 1987-02-18
Abstract: Ink-ribbon cartridges for typewriters or office machines of similar type are subject to different design requirements, the intention being, above all, for them to be easily exchangeable by means of one-handed operation. Since the transporting elements, for example for the carbon ribbon, in cartridges of this type are also mounted in the housing, these cartridges are very expensive. In order to avoid this, ink-ribbon cartridges with exchangeable ink-ribbon spools have been disclosed. The invention is now based on the object of providing an ink-ribbon cartridge with reloadable ink-ribbon spools, which guarantees a simple and reliable exchange of the ink-ribbon spools and permits simple assembly of the cartridge housing (2) with the lid (3). This object is achieved in that the housing (2) and the lid (3) have mutually engageable components of hinges which are moulded on integrally and can be engaged with one another both from the horizontal position of the lid (3) on the housing opening (118) and in the open position of the lid (3) above or at the opening (118). As a result, simple joining-together of the lid (3) and the housing (2) is made possible both by hand and by an automatic joining machine. <IMAGE>
Patent DE-3709741-A1 (DE)
Inventor: GERUM ERICH
IPC: F42C11/00
Filed: 1987-03-25
Abstract: A control circuit 11 for the discharge of an electrical energy store 13 to initiate a munition combat charge 31 is electrically protected against ignition by interference voltages coupled capacitively or inductively into the ignition control line. To this end, a release signal 26 is triggered only if, and when within a gate timespan (predetermined by signal 18) from onset of the ignition signal 17, a predetermined number of control pulses 21 supplied by an asynchronously-working oscillator 22 are counted. The output pulses 34 of the oscillator 22 are converted at 32 to control pulses 21. The oscillator may also control a further counter for triggering a self-destruction charge 43 after a predetermined waiting time. <IMAGE>
Patent DE-3710539-A1 (DE)
Inventor: PUDERBACH MANFRED DIPL ING
IPC: A23G3/22
Filed: 1987-03-30
Abstract: A continuous conveyor chocolate-coating machine has a compact supply and feed device for upper and lower coating devices (9, 10) which can be moved away and decoupled from the conveyor, for cleaning and charging of the coating composition. The circulating circuit for the composition is compact due to the supply container (23) for the lower coating device (9) acting simultaneously as a supply container for precrystallized chocolate entering the circuit. Precrystallized composition is circulated around the circuit by pump (43), the circuit including the upper coating device (10) and supply container (23). Located beneath container (23) is a second supply container (22) which receives uncrystallized composition. The composition is fed by pump (39) through a decrystalliser and precrystalliser, the resultant precrystallized composition being supplied to the circuit. <IMAGE>

Title: Detecting and evaluating earthing mode required - using microprocessor-controlled dialling pulse switch in bilingual telephone subscribers appts.
Inventor: MERKER ANDREAS DIPL ING
IPC: H04M1/53
Filed: 1987-08-04
Abstract: In a procedure for recognition and evaluating the earthing mode needed for dialling, where the telephone station hasa reverse-polarity protecting bridge and a microprocessor-controlled number-dial pulse switch in front of the speech circuit, a keyboard for dialling and a third line for earthing are provided. A controller/evaluator (SA) is provided, with at one input, the potential to be earthed via the third line. The potential criteria are produced via two control points (P1,P2) of the microprocessor (Mp) and are so evaluated that after a dial pulse character the switch interrupts the subscriber line with positive supply potential for a set time. For negative or positive earth demands the third line is coupled to the positive line before the switch or to earth. Zener diodes (D1,D2) provide the supply voltage for the microprocessor during key depression. For zero potential at a switch point (E) the microprocessor can read out criteria to open the switch for a set time.

Title: Alumina tubes and process for their manufacture
Inventor: FRANKFURTER GUENTER
IPC: C01F7/021
Filed: 1988-10-13
Abstract: In a process for the manufacture of a gas-tight alumina tube which is suitable for carrying out catalytic high-temperature reactions, an aqueous suspension of alumina powder is obtained by grinding alumina, a sprayed grain of a grain size of at most 200  mu m is produced from this by spraying, the sprayed grain is presintered at a temperature between 1300 and 1400@C and the presintered sprayed grain is ground with water and a water-soluble additive until the grinding residue on a screen of 63  mu m clear mesh width is 0.2 to 0.4% by weight. The aqueous suspension is then sprayed and the sprayed grain obtained is treated with water and a plasticiser, the mixture is kneaded to give a plastic mass and this is formed by pultrusion into a tubular green body. The latter is likewise presintered at a temperature between 1300 and 1400@C. The presintered tube is immersed in water, briefly dried and the ground mixture of water/additive/sprayed grain is filled into the interior of the tube and the non-adhering remainder is poured out again. Finally, the internally coated tube is dried and dense-sintered at about 1740@C. If desired, it is then impregnated with a solution which contains catalytically active metal ions. The resulting alumina tube carries on the inside an Al2O3 coating having a mean roughness Ra of 2 to 10 mu m.
